Background:
Early embryo implantation is a complex phenomenon characterized by the presence of an implantation-competent blastocyst and a receptive endometrium. Embryo development and endometrial receptivity must be synchronized and an adequate two-way dialogue between them is necessary for maternal recognition and implantation. Proteases have bee...
TRPM3 is a temperature- and neurosteroid-sensitive plasma membrane cation channel expressed in a variety of neuronal and non-neuronal cells. Recently, rare de novo variants in TRPM3 were identified in individuals with developmental and epileptic encephalopathy (DEE), but the link between TRPM3 activity and neuronal disease remains poorly understood...

The transient receptor potential (TRP) channel TRPV2 is widely expressed in a variety of different cell types and tissues. However, elucidating the exact biological functions of TRPV2 is significantly hampered by the lack of selective pharmacological tools to modulate channel activity in vitro and in vivo. This study aimed to identify new compounds...
Transient receptor potential (TRP) channels excel in cellular sensing as they allow rapid ion influx across the plasma membrane in response to a variety of extracellular cues. Recently, a distinct TRP mRNA expression signature was observed in stromal cells (ESC) and epithelial cells (EEC) of the endometrium, a tissue in which cell phenotypic plasti...

The epithelial-to-mesenchymal transition (EMT) is a strictly regulated process that is indispensable for normal development, but it can result in fibrosis and cancer progression. It encompasses a complete alteration of the cellular transcriptomic profile, promoting the expression of genes involved in cellular migration, invasion and proliferation....
Transient receptor potential (TRP) channels play prominent roles in ion homeostasis by their ability to control cation influx. Mouse placentation is governed by the processes of trophoblast proliferation, invasion, differentiation, and fusion, all of which require calcium signaling. Although certain TRP channels have been shown to contribute to mat...
Calcium (Ca²⁺) is one of the most universal secondary messengers, owing its success to the immense concentration gradient across the plasma membrane. Dysregulation of Ca²⁺ homeostasis can result in severe cell dysfunction, thereby initiating several pathologies like tumorigenesis and fibrosis. Transient receptor potential (TRP) channels represent a...
Endometriosis is a prevalent gynecologic disease, defined by dysfunctional endometrium-like lesions outside of the uterine cavity. These lesions are presumably established via retrograde menstruation, i.e., endometrial tissue that flows backwards during menses into the abdomen and deposits on the organs. As ongoing pain is one of the main pain symp...
Background and Purpose
The transient receptor potential (TRP) ion channel TRPM3 functions as a noxious heat sensor, plays a key role in acute pain sensation and inflammatory hyperalgesia in rodents. Despite its potential as a novel analgesic drug target, little is known about the expression, function and modulation in the humans.
Experimental Appr...
Significance
During pregnancy, the placenta functions as surrogate fetal lungs, kidneys, and gut. Proper placental functioning is therefore paramount during embryonic development. Indeed, placental defects are highly prevalent in mouse mutants showing embryonic death. Here we validate a contrast agent that allows development of the intact placenta...
Successful pregnancy requires the establishment of a complex dialogue between the implanting embryo and the endometrium. Knowledge regarding molecular candidates involved in this early communication process is inadequate due to limited access to primary human endometrial epithelial cells (EEC). Since pseudo-pregnancy in rodents can be induced by me...
Endometriosis is a common gynecological disease that is characterized by the presence of functional endometrial-like lesions in the abdominal cavity. Aside from epithelial cells, these lesions consist of stromal cells that have the capacity to migrate, adhere, proliferate, and induce neuro- and lymphangiogenesis, which allows them to survive at ect...
Calcium plays a key role in many different steps of the reproduction process, from germ cell maturation to placental development. However, the exact function and regulation of calcium throughout subsequent reproductive events remains rather enigmatic. Successful pregnancy requires the establishment of a complex dialogue between the implanting embry...
In this Letter, the trace is missing in Fig. 1e. This error has been corrected online.
Acute pain represents a crucial alarm signal to protect us from injury. Whereas the nociceptive neurons that convey pain signals were described more than a century ago, the molecular sensors that detect noxious thermal or mechanical insults have yet to be fully identified. Here we show that acute noxious heat sensing in mice depends on a triad of t...
Background:
To induce endometrial decidualization in rodents, an intrauterine oil stimulus can be delivered via the nontraumatic vagina or via the traumatic laparotomy. However, there is considerable variation in amount of decidualization using these inducing methods. Therefore, we studied which oil delivery route could achieve the highest rate of...
Decidualization is a progesterone-dependent differentiation process of endometrial stromal cells and is a prerequisite for successful embryo implantation. Although many efforts have been made to reveal the underlying mechanisms of decidualization, the exact signaling between the epithelial cells that are in contact with the embryo and the underlyin...
Study question:
Does mouse endometrial epithelial cells and stromal cells have a similar transient receptor potential (TRP)-channel expression profile and to that found in the human endometrium?
Summary answer:
Mouse endometrial epithelial and stromal cells have a distinct TRP channel expression profile analogous to what has been found in human...
Are members of the transient receptor potential (TRP) channel superfamily functionally expressed in the human endometrial stroma?
The Ca(2+)-permeable ion channels TRPV2, TRPV4, TRPC6 and TRPM7 are functionally expressed in primary endometrial stromal cells.
Intercellular communication between epithelial and stromal endometrial cells is required to...
Significance
The cation channel TRPM3 is highly expressed in the sensory system, where it plays a key role in the detection of noxious heat and the development of inflammatory heat hypersensitivity. Our understanding of the physiological role of TRPM3 in the sensory system and other tissues is hampered by the lack of potent pharmacologic tools, how...
